Some kind of variation on this idea would BE great. I hate whenever you start to get into a round, that stuff.
And then the blob shows up, which in most cases, ends the round in about 15 minutes if the crew works together correctly. It also just feels a bit off logically, in the other 'secret' game modes (traitor, ling, so on) the round ends when they shuttle arrives at CC.
It allows for a ending to the round. The round ending just because syndies have died makes it seem like running into a brick wall when the crew can attempt to repair or call the emergency shuttle (for, you know, emergency's) to end the round.
I would like it from a better RP POV. Allows for logical endings, even if the antags are dead. Like it was said above, the crew can just call the shuttle if they are unable to fix the damage.
